Fixed-price development, no hourly billing

I take fixed-scope development work for products that are already live — fixes, features, integrations, and ongoing maintenance. Every tier has a fixed scope and a fixed price, so you know the cost before we start. I reply within 24 hours and start within 48.

What you can buy

Quick Fix

$99

Fix one bug, adjust one detail, or speed things up.

Good for: A bug blocking a release, a layout broken on mobile, a slow page, a misconfigured redirect.

You get: The fix shipped, plus a short note on the cause and how to avoid it next time.

Small Feature

$299

One contained feature or integration — Stripe, LLM chat, an API endpoint.

Good for: Stripe checkout, LLM chat inside your app, a webhook endpoint, login with one provider.

You get: Working code merged into your repo, with the integration documented.

One Feature

$699

A complete feature, design to code — auth, AI search, a dashboard.

Good for: Auth with roles, AI search over your content, an admin dashboard, an onboarding flow.

You get: Design and code shipped to production, including edge cases and empty states.

Maintenance

$299/mo

Fixes, updates, monitoring — cancel anytime. One request at a time; new features billed separately.

FAQ

What if the scope changes mid-way?

Small adjustments are absorbed. If the work grows beyond the tier, I quote the difference before doing it — you decide.

What if you can't deliver in the stated time?

I flag delays early. If the delay is on me, you can ask for a full refund any time before delivery.

How do refunds work?

Full refund any time before work starts. After delivery, tell me within 7 days if something's wrong and I'll revise it or refund you.

What stack do you work in?

Next.js, React, TypeScript, Tailwind, Node, Cloudflare Workers; AI features on the Anthropic and OpenAI APIs. For anything else, ask first.

Maintenance vs new features?

Maintenance covers fixes, updates, and monitoring — one request at a time. New features are billed separately at the tiers above.

How do we communicate?

Telegram for day-to-day, email for anything formal. I reply within 24 hours.
